The present disclosure provides an injectable and shearing-thinning microbeads gel including a first microgel and a second microgel. The first microgel has a first electric charge and includes a plurality of first gel microspheres. The second microgel has a second electric charge and includes a plurality of second gel microspheres. The first electric charge is opposite to the second electric charge, the average particle size of the first gel microspheres is equal to the average particle size of the second gel microspheres, each of the first gel microspheres includes an acrylic chitosan polymer, an acrylic silk polymer, or a combination thereof, and each of the second gel microspheres includes an acrylic gelatin polymer, an acrylic hyaluronic acid polymer, an acrylic alginate polymer, or a combination thereof.
